Feature classes are homogeneous collections of common features, each having the same spatial representation, such as points, lines, or polygons, and a common set of attribute columns, for example, ...
1. The type of feature represented in a coverage. Coverage es include arcs, nodes, label points, polygons, tics, annotation, links, boundaries, routes, and sections.
CAD feature class
[ESRI software] A read-only member of a CAD feature dataset, comprised of one of the following: polylines, points, polygons, multipatch, or annotation.
representations symbolize layers in a framework that is stored and accessible from within the source geodatabase.
Embedded Feature Class
embedded feature class - [3D GIS] A multipoint feature class embedded into a terrain dataset.
A term used to define coverage elements such as arcs, nodes, or polygons.
feature class1. A classification describing the format of geographic features and supporting data in a coverage.
The To dialog will open, automatically containing the boundary as the Input Features.
Complex Feature Class
A feature class that includes two or more other feature classes (simple or complex).
Complex Polygon ...
The es could be defined gradually, in senses of both variety and deepness. Only such general classes should be defined formally which are acceptable for the majority of all related branches.
Feature class - Feature classes are classifications and representations of geographic features and supporting data in coverages.
Below the layer list there is a set of Export Options These are how you tell sketchup the 3d properties of your buildings.
Set your Extrude Distance Field to be the Roof attribute for each building.
4. What Geodatabase feature classes and rules are supported by the ProjectWise Connector for ArcGIS?
Edge Match An editing procedure to ensure that all features crossing adjacent map sheets have the same edge locations attribute descriptions, and es.
SEC Section table for the section feature class in a coverage. The SEC holds attributes about sections.
For example, the linear feature class might include the subclass "vehicle transportation lines" with the extended data characteristic of "number of potholes.
The semantics associated with an information community (as listed in the OpenGIS Guide) include: metadata to describe the content of feature collections; feature class definitions; attribute definitions; valid feature and attribute relationships; ...
Categories - logical groupings of es and more simplified representation to user
Library - a system that help users to share information around the enterprise ...
Feature Alignment-- The source datasets consists of features from two or more different feature classes that bear some defined relationship to each other.
to binary large object (BLOB) data stored directly in a relational database management system (RDBMS) similar to other vector-based es.
Polygon: A coverage feature class used to represent areas. A polygon is defined by the arcs that make up its boundary and a point inside its boundary for identification. Polygons have attributes that describe the geographic feature they represent.
A coverage used to represent linear features and polygon boundaries. One linear feature can contain many arcs.
In CAD it is a curvilinear feature defined by such location combinations as Center point, radius, and starding point.
Various types of geographic datasets can be collected within a geodatabase, including feature classes, attribute tables, raster datasets, network datasets, topologies, and many others.
A shapefile is a vector data format for storing the location, shape, and attributes of geographic features. A shapefile is stored in a set of related files and contains one .
Scalable Vector Graphics ...
Extracted coordinates for features from scanned maps or aerial photographs may be complex and will rely on sophisticated, line-following algorithms or feature classification and extraction algorithms to obtain the desired information from the map or ...
These include themes, coverages, layers, levels, objects, and es. Data layer and theme are the most common and the least proprietary to any particular GIS software and accordingly, as used throughout the book.
